Refers to design and installation of walls, barriers, doors, windows, vents, means of egress, etc. integral to and incorporated into a building or structure in order to minimize danger to life from fire, smoke, fumes or panic before the building is evacuated. These features are also designed to achieve, among others, safe and rapid evacuation of people through means of egress sealed from smoke or fire, the confinement of fire or smoke in the room or floor of origin and delay their spread to other parts of the building by means of smoke sealed and fire resistant doors, walls and floors. It shall also mean to include the treatment of buildings components or contents with flame retardant chemicals.

The industrial process of subjecting materials to heat for the purpose of removing solvents or moisture from the same, and/or to fuse certain chemical salts to form a uniform glazing the surface of materials being treated.

A rocket or liquid propellant which consist of combinations of fuels and oxidizers which ignite spontaneously on contact with each other.

Descriptive of materials that are easily set on fire.

Any material or mixture consisting of a fuel and oxidizer used to set off explosives.

Type or burner where the fuel is subjected to pressure prior to discharge into the combustion chamber and/or which includes fans or other provisions for the introduction of air at above normal atmosphere pressure into the same combustion chamber.

Materials used as final coating of a surface for ornamental or protective purposes.

An extremely hot luminous bridge formed by passage of an electric current across a space between two conductors or terminals due to the incandescence of the conducting vapor.

Descriptive of any substance that ignites spontaneously when exposed to air.
